How to determine your Apple part number through the IEEE Code.

All Apple logic boards and other sub-assemblies have what is known as an eee code in the serial number.  This eee Code is used to determine exactly which computer the part is from.  Typically the code is three digits long and is in the last four digits of the serial number but now there are as many as four in the last six digits.  So, if we ask you for a eee code what we want are the last six digits of the serial number on the board or part.  If there is no seral number we may ask for the etch number which is typically a number on the board that starts with 820-xxxx.

How to determine my computer model

If you need to figure out the bulild of your computer you can check it directly with Apple with the serial number.  You can obtain the serial number from the "About this Mac" under the Apple if your computer is still working.  If not, on most laptops it's on the bottom or under the battery, iMac's are on the bottom, and Mac Pro's are on the back.

Once you've located the serial number go to link below and type it in, Apple will tell you the build of your computer, i.e. iMac 24-inch (Early 2009), etc.
